Detailed Description

A proxy from a FunctionAnalysisManager to an SCC.

When a module pass runs and triggers invalidation, both the CGSCC and Function analysis manager proxies on the module get an invalidation event. We don't want to fully duplicate responsibility for most of the invalidation logic. Instead, this layer is only responsible for SCC-local invalidation events. We work with the module's FunctionAnalysisManager to invalidate function analyses.
